摘要
Disclosed is a method performed by a network node (130, 140, 160) of a wireless communication network (100) comprising a first (130) and a second (140) core network node and a first (150) and a second (160) base station (150). A session of a wireless device (170) comprises data packets routed via a plurality of anchor network nodes (115, 120) from a data network (110).In connection with the wireless device (170) handing over from the first base station (150) and the first core network node (130) to the second base station (160) and the second core network node (140), the method comprises receiving information of the number of the plurality of anchor network nodes (115, 120) via which data packets of the session are routed, receiving data packets from the plurality of anchor network nodes (115, 120), receiving an end marker of each of the plurality of anchor network nodes (115, 120), each end marker indicating a last data packet of one of the plurality of anchor network nodes routed via the first core network node (130), and when the number of received end markers equals the number of the plurality of anchor network nodes, triggering to send to the wireless device (170) any data packets related to the session not routed via the first base station stored in a buffer of the second base station.
